Njengamanje, umthamo wokusetshenziswa kwe-polyethylene ezweni lami likhulu, futhi ukuhlukaniswa kwezinhlobo ezingezansi komfula kuyinkimbinkimbi futhi ikakhulukazi kuthengiswa ngqo kubakhiqizi bemikhiqizo yepulasitiki.Iyingxenye yomkhiqizo wokugcina ochungechungeni lwemboni esezansi nomfula i-ethylene.Ngokuhambisana nomthelela wokugxilwa kwesifunda kokusetshenziswa kwasekhaya, igebe lesifunda kanye nesidingo alilingani.
Ngokukhula okugxilile kwamandla okukhiqiza amabhizinisi okukhiqiza e-polyethylene akhuphuka nomfula wezwe lami eminyakeni yamuva nje, uhlangothi lokuhlinzeka lukhule kakhulu.Ngesikhathi esifanayo, ngenxa yokuthuthukiswa okuqhubekayo kokukhiqizwa kwabahlali kanye namazinga okuphila, isidingo sabo siye sakhula kancane kancane eminyakeni yamuva.Kodwa-ke, kusukela engxenyeni yesibili ka-2021, isimo samazwe ngamazwe besikhohlisa futhi siyashintsha.Ukubhebhetheka kwalolu bhubhane kanye nezimpi zasekhaya kuholele ekungalinganini ohlelweni lwezimali lwamazwe ngamazwe oluphathelene nogesi.bhidlika.Ukungaqiniseki okwandayo emnothweni omkhulu kuqhube imizwa yokudliwa kwezakhamuzi yafinyelela esigabeni sokuqapha.Ngaphansi kwesimo samanje, izingozi nezinselele ezibhekene nokuthuthukiswa kwemikhiqizo ye-polyethylene nazo zinzima kakhulu.
Ukuthuthukiswa kwabantu nomnotho kunquma ukusatshalaliswa kokusetshenziswa kwe-PE.Ngokombono wezifunda ezisetshenziswayo ezansi nomfula, i-East China, i-South China, neNyakatho ye-China yizindawo ezisetshenziswa kakhulu zokusetshenziswa kwe-polyethylene ezansi nomfula ezweni lami, futhi zizohlala ziphezulu ezintathu mayelana nokusetshenziswa isikhathi eside.Nokho, njengoba kwethulwa ngokuqhubekayo imishini emisha yokukhiqiza esikhathini esizayo, kulindeleke ukuthi igebe lokusetshenziswa ezindaweni ezintathu ezinkulu ezisetshenziswayo linciphe ngezinga elithile.Kulindeleke ukuthi lokhu kuzothinta kakhulu ukuhlinzekwa kwephethini yesikhathi esizayo nesidingo kanye nokugeleza komkhiqizo ezifundeni ezinkulu.Kuhle futhi ukubalula ukuthi nakuba ingxenye yesidingo esingaphansi komfula esifundeni esisentshonalanga sincane kunaseMpumalanga China, iNingizimu China, neNyakatho neChina, eqhutshwa yizinqubomgomo zasekhaya ezifana ne-"One Belt, One Road" kanye "neNtuthuko YaseNtshonalanga", ukusetshenziswa phansi komfula kwe-polyethylene esifundeni esisentshonalanga kuzokwanda esikhathini esizayo.Kunokwenyuka okulindelekile, ikakhulukazi emikhiqizweni efunwa yingqalasizinda eholwa ngamapayipi, futhi isidingo sokubumba umjovo kanye nemikhiqizo yokubumba ejikelezayo elethwa ukuthuthukiswa okuqhubekayo kwezinga lempilo kusobala kakhulu.
Khona-ke, mayelana nezinhlobo ezisetshenziswayo ezansi nomfula esikhathini esizayo, hlobo luni lwentuthuko elindelwe izinhlobo eziyinhloko zesidingo se-polyethylene ezizoba nazo?
Njengamanje, ukusetshenziswa okuyinhloko kwe-polyethylene ezweni lami kuhlanganisa ifilimu, ukubunjwa komjovo, ipayipi, okungenalutho, umdwebo wezintambo, ikhebula, i-metallocene, i-coating nezinye izinhlobo eziyinhloko.
Eyokuqala ethwele kanzima, ingxenye enkulu yokusetshenziswa komfula ifilimu.Embonini yomkhiqizo wamafilimu, okujwayelekile ifilimu yezolimo, ifilimu yezimboni kanye nefilimu yokupakisha yomkhiqizo.Kodwa-ke, eminyakeni yamuva nje, izici ezifana nemingcele ezikhwameni zepulasitiki kanye nokuncipha okuphindaphindiwe kwesidingo ngenxa yalolu bhubhane ziye zabakhathaza ngokuphindaphindiwe, futhi babhekene nesimo esinamahloni.Isidingo semikhiqizo yamafilimu epulasitiki alahlwayo kancane kancane sizothathelwa indawo ukuthandwa kwamapulasitiki awonakele.Abakhiqizi abaningi bamafilimu nabo babhekene nezindlela ezintsha zobuchwepheshe bezimboni, futhi kancane kancane bathuthukela kumafilimu ezimboni angasebenza kabusha anekhwalithi nokusebenza okuqinile.Kodwa-ke, ngenxa yokonakala kwamafilimu epulasitiki awonakaliswayo, kunezidingo eziqinile zokupakishwa kwangaphandle, noma isidingo samafilimu okupakisha angaphandle adinga ukugcinwa isikhathi eside esidlule isikhathi sokuwohloka, futhi amafilimu ezimboni kanye neminye imikhakha ayikashintsheki, ngakho imikhiqizo yefilimu isazosetshenziswa.Kuye kwaba khona njengomkhiqizo oyinhloko phansi komfula we-polyethylene isikhathi eside, kodwa kungase kube nokwehla kokukhula kokusetshenziswa kanye nokwehla kwesilinganiso.
Ngaphezu kwalokho, izimboni ezifana nokubumba umjovo, amapayipi, nemigodi ehlobene eduze nokukhiqizwa nokuphila zisazoba yimikhiqizo eyinhloko yabathengi ezansi nomfula we-polyethylene eminyakeni embalwa ezayo, futhi zisazobuswa yingqalasizinda, izidingo zansuku zonke, kanye nezomphakathi. amathuluzi nemishini.Impilo yabantu ixhumene nempahla ehlala isikhathi eside, futhi isidingo sokuwohloka kwemikhiqizo siyehla.Njengamanje, inkinga enkulu ebhekene nalezi zimboni ezingenhla ukuthi izinga lokukhula komkhakha wezindlu ezithengiswayo liwenzile eminyakeni yamuva nje.Ngenxa yezinto ezifana nempendulo engemihle mayelana nokusetshenziswa kwezakhamuzi okulethwa izifo eziwumshayabhuqe eziphindaphindayo, ukuthuthukiswa kwemboni yemikhiqizo kubhekene nokumelana nokukhula okuthile.Ngakho-ke, ukuguqulwa kwesilinganiso sesikhathi esifushane kulinganiselwe, futhi akuthintwa kancane yimikhiqizo yokuwohloka.Imboni yamapayipi kungenzeka ukuthi ithikamezeke yizinqubomgomo, kuyilapho ukubumba umjovo kanye nemikhiqizo engenalutho kuthinteka kakhulu imizwa yokusetshenziswa kwezakhamuzi, futhi izinga lokukhula lizokwehla esikhathini esizayo.kungenzeka.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ukusungulwa komuntu ngamunye kanye nokwenza abantu kwemikhiqizo yepulasitiki, kanye nokuqanjwa kwekhwalithi yomkhiqizo kanye nezidingo zokukhiqiza ezenziwe ngezifiso nakho kuthuthuka njalo.Ngakho-ke, esikhathini esizayo, imboni yemikhiqizo yepulasitiki izokwandisa isidingo sezinto ezithile zokusetshenziswa ezithuthukisa ukusebenza kwemikhiqizo yepulasitiki, njenge-metallocenes, amapulasitiki aginqikayo, izinto zokumboza kanye neminye imikhiqizo enenani eliphakeme noma imikhiqizo enezidingo ezihlukile emikhakheni ekhethekile. .Ngaphezu kwalokho, ngenxa yokukhiqizwa okugxilile kwamabhizinisi okukhiqiza i-polyethylene enhla nomfula eminyakeni yamuva, okuholele ekuguquguqukeni okukhulu komkhiqizo, futhi ukungqubuzana phakathi kweRussia ne-Ukraine phakathi nonyaka kubangele amanani aphezulu kawoyela ukuthi anyuse inzuzo ye-ethylene, kanye nokwanda kwezindleko. futhi ukunikezwa kuholele ekufaniseni komkhiqizo okungathi sína.Ngaphansi kwesimo samanje, Abakhiqizi be-polyethylene basebenza kakhulu ekukhiqizeni imikhiqizo ephezulu ye-value-added efana ne-metallocenes, ukubunjwa okujikelezayo, kanye nama-coatings, ngokuhambisana nokuthuthukiswa kwezimboni ezingezansi.Ngakho-ke, izinga lokukhula kwemikhiqizo lingase lenyuke ngezinga elithile esikhathini esizayo.
Ngaphezu kwalokho, njengoba lolu bhubhane luqhubeka ngokuphindaphindiwe, kanye nokucwaninga nokuthuthukiswa kwemikhiqizo emisha ngabakhiqizi, imicu ye-polyethylene, izinto ezikhethekile zomkhiqizo wezokwelapha nezokuvikela nazo zilandelwa kancane kancane futhi zathuthukiswa, futhi isidingo sesikhathi esizayo sizokhula kancane kancane.
